Add-on Compatibility for Firefox 17

Jorge Villalobos

15

Firefox 17 will be released on November 20th. Here’s the list of changes that went into Firefox 17 that can affect add-on compatibility. There is more information available in Firefox 17 for Developers, so you should read that too.

General

XPCOM

New!

Additionally, the load handler problem that appeared in Firefox 16 should now be fixed in Firefox 17.

Please let me know in the comments if there’s anything missing or incorrect on these lists. If your add-on breaks on Firefox 17, I’d like to know.

The automatic compatibility validation and upgrade for add-ons on AMO will happen next week, so check your email.

    Link text in first paragraph should read “Firefox 17 for Developers” (not 16).

    My Stay-Open Menu version 2.0 breaks on Firefox 17, but an updated version 2.0.1 with the fix has already released on AMO.

    my addins work all, but version 17 seems to have Javascript issues. Some forum software like IPB is partial broken in Firefox 17 for me.

      Firefox 18 Beta 2 fixed it for me.

      And the bug 590755 doesn’t show any recent activity. Sigh. The Tab Utilities’ developer mentions that he probably can to catch Fx for the release 18 or 19:

      Is there a method to check your active Firefox add-on usage before upgrading?

      (What would be nice in the Firefox options for upgrading is to allow upgrades only once all actively used add-ons have full support in the new Firefox version. After all computers should do what they do best, admin work, such as checking and cross checking status of items.)

    Thanks for this information.

    What about E4X ? I get conflicting information between
    https://developer.mozilla.org/en-US/docs/E4X
    that says ” E4X is deprecated. It will be disabled by default for content in Firefox 16, disabled by default for chrome in Firefox 17, and removed in Firefox 18.”
    and
    https://developer.mozilla.org/en-US/docs/Firefox_17_for_developers
    that says E4X is disabled for content in FF 17

    And I see it still working for chrome in release 18.0a2

    I have created a document bug : https://bugzilla.mozilla.org/show_bug.cgi?id=811746 just in case.

    Thanks !

    PS: sorry if this got posted several time, using Google Chrome browser I got a blank page, and retried.
    PPS: sorry for using Google Chrome.

    IT IS ALL WELL AND GOOD THAT YOU FIX BUGS, UPDATE/MAKE BETTER (BETTER THAN WHAT?) FIREFOX. BUT HERE I SIT, 45 MIN., A TOTAL BEGINNER, (READ: “EMBRYO,”) AT THIS WHOLE NET/FF/et al-THING (I HAVE INTERNET SINCE SEP. 2012-STAYING IN FRANCE FOR THE MOMENT), AND NOW HAVE LOST THE PERFECT (MY POINT OF VIEW) TAB MIX PLUS, WHICH FF SIMPLY ANNOUNCED, A F T E R, I HAD UPDATED TO FF17, IS NOT COMPATIBLE WITH FF17. CAN ANYONE TELL ME WHICH ADD ON FOR MY TABS IS AS GOOD AS (READ: EASY TO USE AND UNDERSTAND) AS TAB MIX PLUS? OR, HOW DO I UN-UPDATE TO FF17? HELP…LOST I AM.

      We recommend that you keep the add-on disabled until the new version is released. We know the developer is working on a fix, so it will probably be available soon.

        I see a big
        “NEXT VERSION UPDATE WILL BE ON JANUARY 2013″

        in the main page of Tab Mix Plus in amo.

        “Works with Firefox 4.0 and later”
        At least the compatibility info should to be updated…

          If you try installing it now, Firefox should tell you it’s incompatible. AMO will continue saying it is compatible with 4.0 and later, unfortunately.

    Since update 17 some javascript seems to be broken for my website too, the menus with hover over display don’t display at all. The javascript comes from a DotNetNuke menu.

      Install the Firefox 18 Beta 2. This fixed it for me.

    Add on developers can’t keep up with this ridiculous rapid release cycle, that constantly disables addons .

    This negates the main reason for using Firefox.

    Might as well switch to Chrome or IE.
